Help! My Furnace Fuse Keeps Blowing

Help! My Furnace Fuse Keeps Blowing

If your furnace keeps blowing a fuse, it is important to act quickly to find out what the problem is and to get it taken care of as quickly as possible. While replacing the fuse in the unit’s fuse panel or resetting the breaker can be a temporary fix, the fuse will keep blowing if the underlying issues aren’t taken care of properly. Keeping your family and home safe and protected is a top priority, so keep reading to learn what could be causing the issue and how to take care of it!

Why Does My Furnace Keep Blowing a Fuse?

Furnace panel fuse blown? This may happen on occasion. But if your furnace fuse is blowing repeatedly, you may have a problem with:

  • Dirt and Dust
    Cleaning your furnace filters should be a part of your regular home maintenance schedule. Over time, dust and debris can make its way from the filters into the blower motor. This can cause the motor to overheat and eventually burn out. This can cause the furnace to blow a fuse and turn off.
  • Loose Wires
    Wires can loosen over time due to the natural vibrations of a working furnace. If a wire becomes loose, it can short out, causing the fuse to blow. Because locating and fixing the loose wire can be a difficult task on your own, it’s important to contact HVAC professionals for help. Also, regular furnace inspections will help make sure all wires are tight and secure.
  • Faulty or Worn Parts
    Over time, parts of the furnace may break down due to regular usage and age.
  • Water Leaks
    It is not uncommon for there to be an occasional water leak in your furnace from an attached or nearby humidifier. However, if not taken care of right away, water leaks may damage your unit. Calling in the professionals to take care of any leaks will ensure no further damage to the furnace.
  • Failing Valves
    If you have a gas furnace with a fuse that keeps blowing, check the safety valve on the furnace. It should be able to open and close when needed. If the valve is clogged, it may be keeping too much heat inside the unit or forcing too much heat out. This may cause the furnace to overheat, potentially causing a fire.
  • Wrong Fuse
    If the furnace has incorrect fuses installed, it could be causing the fuse to blow. The professionals at Aire Serv can diagnosis this problem and install the correct size fuse.
  • Malfunctioning Thermostat Wire
    In an electric furnace, if the thermostat wire touches the metal frame of the furnace, it can cause a blown fuse. When the wire touches the metal frame, it can deliver a higher voltage than the wires are meant to handle. This will cause a fuse to blow. When this happens, the rest of the furnace stops functioning properly.
